Buzz Stocks: Tyson Foods, Inc., Canadian Solar Inc., and Lifelock Inc

U.S. stocks are higher on ballooning oil prices. Among specific equities in focus today are chicken producer Tyson Foods, Inc. (NYSE:TSN), solar energy stock Canadian Solar Inc. (NASDAQ:CSIQ), and identity theft specialist Lifelock Inc (NYSE:LOCK). Here's a quick look at what's driving TSN, CSIQ, and LOCK today.

• TSN is trading 16.1% lower at $56.49 -- on the short-sale restricted list -- after the company reported an earnings miss and announced that its current president, Tom Hayes, will be stepping in to replace Donnie Smith as CEO at the end of the year. And while TSN still sits up 6% in 2016, the stock is down 27% since notching an all-time high of $77.05 in early September. In the option pits, a few option bulls may be sweating, with Tyson Foods, Inc.'s 10-day call/put volume ratio at the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX) of 1.83 sitting in the 80th percentile of its annual range.

• CSIQ is down 7.2% at $10.86, after the company downwardly revised its full-year forecast due to shipping capacity issues. CSIQ has taken it on the chin so far in 2016, surrendering 62.5% -- and dropping 18.4% since the solar sector began its post-election plunge. Short sellers have been cashing in their winning chips recently, too, with short interest down 15.3% in the two most recent reporting periods. Nevertheless, short interest still accounts for a lofty 15.6% of CSIQ's available float, or 6.7 times its average daily pace of trading.

• LOCK is  up 14.9% at $23.84, on news that cybersecurity firm Symantec Corporation (NASDAQ:SYMC) would be purchasing the cybersecurity firm in a deal valued at $2.3 billion, or $24 per LOCK share. Lifelock Inc now sits up nearly 67% in 2016, and notched a new all-time high of $23.98 earlier today. Amidst recent buyout rumors, option buyers have been especially call-skewed, with LOCK's 10-day ISE/CBOE/PHLX call/put volume ratio docked at a top-heavy 35.74.
